The Pink Flamingo Kid - S3-E17
Mr. Feeny: I'm frustrated to see two young men throw away a friendship.
Shawn: Yeah, well the way I see it Mr. Feeny, you don't need friends. OK, especially friends like him.
Mr. Feeny: Then who do you count on, Mr. Hunter?
Shawn: Family. Your family is always there for you. Come on, Mr. Feeny, a guy like you with no friends, you gotta know I'm right.
Chosen answer: In the present day, with the United States abiding by more stricter school health laws, for the most part this wouldn't be in school cafeterias as many cannot even have carbonated beverage machines now. However, in the 90s when the show takes place, it wasn't unheard of for there to be coffee machines in the cafeteria of small schools where the teachers eat with the students as we see them do often in the show. The idea being that the cafeteria was small enough so a teacher or hall monitor could catch a student before they could drink the coffee.
